Description

This passive twinax copper breakout direct attach cable connects one OSFP port, configured for 200G over 8x25G NRZ lanes, to two 100G QSFP ports (200GBASE-CR8 to 2x100GBASE-CR4). At 2 meters in length, it suits short-reach server and NIC breakout and the connection of legacy 100G QSFP ports within the rack or to an adjacent rack.

Enquire with XS Network Tech for new or used pricing and availability.

FAQs

Q: What does this cable connect?
A: It connects one OSFP port running at 200G (8 x 25G NRZ lanes) to two 100G QSFP ports using a passive twinax copper breakout design.

Q: Does the OSFP port need any special configuration?
A: Yes. The OSFP port must be configured for 200G using 8 x 25G NRZ electrical lanes. The minimum supported EOS version is 4.23.0.

Q: Can it be used with server NICs from other vendors?
A: Yes. The EEPROM is programmed for up to 25G NRZ data rates, which supports legacy NICs that only recognise 25G signalling, making it suited to connecting Arista switches to non-Arista equipment.

Q: Is this an active or passive cable?
A: It is a passive twinax copper cable, so there are no optical components and no wavelength specification.

Q: What other lengths are in this range?
A: The CAB-O-2Q-200G-xM family is available in 1 m, 2 m and 3 m lengths. This SKU is the 2 meter version.
